Branches of the Cenél Conaill

The Cenél Conaill, or "kindred of Conall", are a branch of the Northern Uí Néill, who claim descent from Conall Gulban, son of Niall of the Nine Hostages, and allegedly the first Irish nobleman to convert to Christianity. Their kingdom was known as Tír Conaill, with their powerbase at Mag Ithe in the Finn valley, however they gradually expanded to cover what is now present-day counties Donegal and Fermanagh. The Cenél Conaill clashed regularly with their kin the Cenél nEogain, eventually capturing the latters original power-base of Ailech in the Inishowen peninsula—in modern-day County Donegal—by the 12th century.

Below is a list of their principle clans and septs.
